See section 7.7.1 on setting up over a mark on the floor or ground using the laser plummet

9.5 Correction of atmospheric influences

The tool uses a visible laser beam for distance measurement.
As a fundamental principle, when light passes through the air its speed is reduced due to the density of the air.
This influence varies according to the air density.
Air density depends to a great extent on air pressure and air temperature and to a significantly lesser extent on air
humidity.
If distances are to be measured accurately it is essential that atmospheric influences are taken into account.
The tool calculates and corrects the corresponding distances automatically, but the temperature and pressure of the
surrounding air must first be entered.
These parameters can be entered in various units.
Switch the laser pointer on/off.
Switch display illumination on/off
or vary its intensity. The brighter
the display, the more power is
consumed.
